Following my update earlier in the week, I have now had advice from TMR as below.
Thank you for your enquiries seeking an update on the review of temporary traffic signal arrangements for Maleny-Kenilworth Road and Maleny-Stanley River Road. I apologise for the delay in responding.
The Transport Network Reconstruction Program (TNRP) team has undertaken investigations on the existing temporary traffic signals to determine whether alternative traffic control measures can be implemented at these sites. These investigations determined that temporary signals will need to remain in place on Maleny-Stanley River Road and at the Maleny-Kenilworth Road site near Scrubby Creek due to the location of the damage and the topography of these sites.
At the traffic signals site on Maleny-Kenilworth near Bakers Road, an option to widen the road and remove the temporary signals is being further investigated.
The TNRP team is also investigating the viability and effectiveness of installing vehicle-actuated temporary traffic signals, rather than signals operating on timing. Further information is being sought on vehicle-actuated signals and their capacity to detect motorcycles, and also their availability.
I trust this information is of assistance. Further information will be provided once it is available to the TNRP team.
Update 24 January 2012
I have had quite a few people make contact with me about the use of the traffic signals along Maleny-Kenilworth Road and Maleny-Stanley River Road that are both operating with one land closed due to the floods of 2011. Following a briefing in November last year and subsequent written notification, the Department of Transport and Main Roads (TMR) had advised they were investigating the use of the traffic signals and whether other traffic control measures could be employed at these sites and would provide me with the results of their investigations. My office has followed up with TMR twice since November and we are still waiting on a response.
